Hej!
Mam następujący problem:
Posiadam kartę wifi usb na chipsecie Ralink2070. Wszystko działa cacy do momentu kiedy podłączam do laptopa dysk twardy SATA w obudowie usb. Otóż gdy montuję dysk, po paru minutach karta wifi przestaje reagować, led od karty przestaje się palić i zrywa połączenie z siecią.
Kiedy wpisuję

Kod: Zaznacz cały

iwconfig
ifconfig

lub:

Kod: Zaznacz cały

./networking restart

konsola "zamarza" i nie pokazuje się żaden komunikat. Dopiero po wyjęciu karty konsola się odwiesza i informuje, że nie ma żadnych urządzeń sieciowych itd. Gdy odłączam dysk i robię restart wszystko powraca do normy i mogę cieszyć się []połączeniem z internetem[/b] non stop, ale niestety bez podłączonego hdd.
Nie wiem czy to coś da, ale podam:

Przejrzyj logi, może w nich coś ciekawego się znajduje.

Podłączyłem dysk, karta się zwiesiła, wyjąłem kartę i włożyłem ponownie (niestety karta nie ruszyła).
Log pokazał coś takiego:

Możliwe, że dysk zabiera za dużo napięcia i dla karty wifi już nie wystarcza. Spróbuj podłączyć dysk do innych portów usb. Innym rozwiązaniem jest podłączenie przez zasilany hub. Wtedy sprawdzisz, czy sprzęt ma wystarczająco prądu.

[DaVidoSS]

Otwórz terminal i wykonaj:

Kod: Zaznacz cały

su
tail -f /var/log/messages

Wykonaj czynność powodującą rozłączenie wifi. Pokaż nam to co pojawi się w terminalu.

Proszę bardzo. Po odłączeniu wifi:

odczekałem parę minut i nic więcej się nie pojawiło, więc wyjąłem kartę i włożyłem:

Gdy dysk jest zamontowany wifi już nie wstaje. Po wpisaniu:

Kod: Zaznacz cały

ifconfig wlan0 up

konsola nie odpowiada, a dopiero po wyjęciu karty z usb terminal działa z powrotem. Pomaga dopiero odmontowanie partycji dysku (z gniazda usb nie wyciągam)i wtedy bez problemów

ifconfig

i

Przecież paolus już podał przyczynę. Port usb nie dostarcza nieograniczonej ilości energii, w dodatku w laptopie.
http://pl.wikipedia.org/wiki/Usb#Transmisja_elektryczna

Akurat problem stanowi ograniczona wydajność prądowa (natężenie) portów usb. 500mA do zasilania dysku twardego i karty wifi to stanowczo za mało. W laptopach wydajność prądowa nigdy (albo bardzo rzadko) osiąga nominalne natężenie 500mA.

[mgR_Lobo]

Dysk jest zasilany przez zewnetrzny zasilacz, a nie przez usb.

[fnmirk]

A magistrala sygnałowa USB nie obciąża? Przecież też posiada ograniczenia. Jeżeli w laptopie wydajność prądowo napięciowa portów usb mieści się w dolnej granicy dopuszczalnej tolerancji to podpięcie karty wifi (jest to jednak nadajnik i wymaga energii, tu nic nie oszukasz) powoduje zanik napięcia. Taki efekt może wywołać każde urządzenie. Wystarczy, że używałeś go w jakiś niewłaściwy sposób.
Przepięcia elektrostatyczne są tu głównym wrogiem, powodują zmiany (lub uszkodzenia) elementów biernych i czynnych urządzenia. W domowych warunkach są nie do znalezienia. Wspominam o tym bo nieraz widzę jak użytkownicy traktują tego typu urządzenia przenośne.
Wyładowania elektrostatyczne towarzyszą nam na każdym kroku. Najczęściej niewidoczne i wtedy pada pytanie przecież nic się nie stało. Wystarczy w samochodzie wyjmować i wkładać np. kartę wifi i prawdopodobieństwo uszkodzenia jest bardzo duże. Uwagi o ładunkach elektrostatycznych są w prawie każdej dobrej instrukcji obsługi, ale kto o nich pamięta skoro elektronów nie widać.

Sprawdź w pierwszej kolejności sprzęt. A czy jest to wina systemu najlepiej sprawdzisz korzystając z jakiejś dystrybucji uruchamianej z płytki cd/dvd.

Knoppix będzie odpowiedni.

Może to być, lecz z ciekawości na moim laptopie (ACER Aspire) podłączałem co miałem w tym dysk USB i karty USB-WLAN nie wypina.
